Description

Technical Field

[0001] This utility model relates to an air filter element, specifically a folded air filter element suitable for high-efficiency dust removal. Background Technology

[0002] Traditional flat or simple pleated filter cartridges have limited effective filtration area, resulting in high air resistance and high load per unit area. This limits the improvement of their filtration efficiency and dust holding capacity, requiring frequent replacement and failing to meet the demand for "high-efficiency dust removal".

[0003] Traditional filter cartridges (especially those with large pleats) lack effective internal support. When encountering strong airflow impacts, equipment vibrations, or high air humidity, the filter media is prone to collapse, wrinkling, and sticking together. This leads to a reduction in effective filtration area, uneven or even increased air resistance, and may create airflow short-circuit channels, allowing unfiltered air to pass through, severely reducing the filter cartridge's lifespan and filtration reliability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a folded air filter element suitable for high-efficiency dust removal, so as to solve the problems existing in the background art.

[0005] This utility model is applicable to a folded air filter element for high-efficiency dust removal, which is achieved through the following technical solution, including a filter element fixing base, a folded filter element assembly, a front dustproof baffle, and a rear air purification baffle.

[0006] Both the front dust baffle and the air purification baffle are positioned at the front and rear ends of the filter element fixing seat through a positioning structure.

[0007] The pleated filter element assembly is inserted into the filter element fixing seat from top to bottom, and is supported by the skeleton structure to prevent the filter material from collapsing and sticking under airflow, vibration or moisture conditions.

[0008] As a preferred technical solution, the pleated filter element assembly includes a mounting bracket with a "door"-shaped structure and a filter media body;

[0009] The filter media body is fixed to the inside of the mounting bracket by bonding, thereby realizing the installation between the filter media body and the mounting bracket.

[0010] As a preferred technical solution, the filter element fixing seat is hollow to form a filter chamber, and an insertion groove is provided on the top of the filter element fixing seat. The mounting bracket is inserted into the insertion groove from top to bottom.

[0011] The skeleton structure is set inside the filter chamber. When the folded filter element assembly is inserted into the filter chamber, the skeleton structure supports the filter material body.

[0012] As a preferred technical solution, the filter media body is serrated, and the skeleton structure includes multiple support plates, which match the serrated path of the filter media body, thereby providing support for the filter media body.

[0013] As a preferred technical solution, the positioning structure includes a positioning block and a silicone ring disposed on the front dustproof baffle and the rear air purification baffle;

[0014] The silicone ring is located on the outside of the positioning block. When the positioning block is placed in the filter chamber at the front or rear end of the filter element fixing seat, the silicone ring is squeezed to achieve a fixing effect.

[0015] As a preferred technical solution, a dustproof net is provided on the front dustproof baffle, and an activated carbon filter is provided on the rear air purification baffle.

[0016] As a preferred technical solution, a removal handle is provided on the top of the mounting bracket.

[0017] The beneficial effects of this utility model are:

[0018] This invention uses a folded filter material body, which significantly increases the effective filtration area, reduces wind resistance, and improves air filtration efficiency and dust holding capacity; the post-activated carbon filter can further adsorb odors and harmful gases, enhancing the air purification effect.

[0019] This invention features a built-in skeleton structure (support plate) that matches the serrated path of the filter media, effectively supporting the filter media and preventing it from collapsing or sticking under airflow impact, vibration, or damp conditions, thus ensuring the long-term stable operation of the filter element.
